Question

the energy of a particle moving at 5m/s is 125 joule.its mass is?

Answer 1

Hi , friends !!!!

here is your answer!!!

energy is => 125 joule


velocity = 5m/ s


kinetic energy => 1/ 2 mv².


=> 125 joule = 1/2 mass x velocity ².


125 = 1/2 mass x( 5 )².


=> 125 = mass x 1/ 2 x 25


mass = 10 kg



hence , mass is 10 kg



hope it helps you dear!!!

thanks!!
